Glazing system

Abstract

A glazing trim comprising two complementary extrusions having inter-engaging teeth, enable the extrusions to be connected together at different spacings enabling the glazing trim to accommodate sheets of different thicknesses. The glazing trim can be constructed on site by cutting the extrusions to length, and inter-engaging the locking teeth of the complementary extrusions by tilting one of the extrusions about a portion of the other until their teeth engage. A sheet of material can be held in place by resilient gaskets and wedges interposed between the sheet and the extrusions. Several shapes of extrusions are illustrated, together with a variety of different applications for the glazing trim.

I claim: 
     
       1. A glazing trim having a pair of elongate cooperative members, each said member having, in cross section, two limbs substantially at right angles to each other, and engaging means comprising a plurality of teeth on one surface of one of said limbs adapted to interengage at least one tooth on a corresponding limb of said other member, whereby said members can be connected together at different spacings to accommodate sheets of material of different thicknesses therebetween, each of said members having a re-entrant flange on the other said limb which engages a respective resilient member in use between the flange and window pane, wherein the members, once connected together, can be disconnected by removing at least one of said resilient members and tilting said pair of elongate cooperable members relative to each other in a direction such that said re-entrant flanges move toward each other, thereby to disengage said engaging means, one of said pair of elongate cooperable members having thereon a base flange disposed on the side of said one limb that is opposite said re-entrant flange on said one elongate member, said base flange having an upstanding flange that contacts said one limb on the other said elongate cooperable member to limit tilting movement of said elongate cooperable members in a direction such that said re-entrant flanges move away from each other thereby to retain said resilient members and said window pane firmly held between said re-entrant flanges.
